I'm trying to call BUGS from R.  But it's not working.  R freezes up and
BUGS gives me a strange output in the log.  Just to know, BUGS is
registered.  The modified date on the keys file is today (Dec. 9th).  It
should be fully registered so that I can use it fully.  And, the BUGS model
is syntactically correct.  Any suggestions would be very helpful.

Here is my BUGS model:
model {
    for (i in 1:n){
        y[i] ~ dnorm (y.hat[i], tau.y)
        y.hat[i] <- a[county[i]] + b[county[i]]*x[i]
    }

for (j in 1:J){
    a[j] ~ dnorm (0, .0001)
    b[j] ~ dnorm (b.hat, tau.b)
    }

b.hat ~ dnorm (0, .0001)
tau.b <- pow(sigma.b, -2)
sigma.b ~ dnorm (0, 100)
tau.y <- pow(sigma.y, -2)
sigma.y ~ dunif (0, 100)
}


Here is my R code used to call BUGS:
y <- abs.4diff
n <- length(abs.4diff)
x <- log.ineq

uniq.name <- unique(country_name)
J <- length(uniq.name)
country <- rep (NA, J)
for (i in 1:J){
    country[country_name==uniq.name[i]] <- i
}

ineq.bugs <- list ("n", "J", "y", "country", "x")
ineq.inits <- function (){
    list(a=rnorm(J), b=rnorm(J), b.hat=rnorm(1), sigma.y=runif(1),
sigma.b=runif(1))}
ineq.parameters <- c("a", "b", "b.hat", "sigma.y", "sigma.b")

ineq1 <- bugs (ineq.bugs, ineq.inits, ineq.parameters, "C:/Documents and
Settings/Chris/Desktop/4330/attempt2.bug", n.chains=3, n.iter=10,
debug=TRUE)



After I run the R code, R will crash and WinBUGS14 will post this in the
log:

I'm not sure what "(is greyed out)" means.  But, BUGS supposed give really
poor explanations of its errors.  So, it could mean anything.  Any advice
will be greatly appreciated.


Thank you for your time,
